Instead of a leather strap, todays devices are being attached with using a combination of elastomeric gelatine liners, sockets comprised of carbon fiber and other polymers, passive and active suction, and pin-lock mechanisms. The technology is continuously advancing, but noteworthy hurdles remain in some areas such as comfort, user-intent control, refined device durability, cost, and reimbursement to flesh a few.
